BACKGROUND

The invention relates to electronic controllers that control valves which supply water to sprinklers that irrigate turf, agriculture, and landscaping.

In many parts of the world due to inadequate rainfall it is necessary at certain times during the year to artificially water crops, turf, and landscaping. An ideal irrigation system for crops, turf, and landscaping should utilize valves, supply lines, and sprinklers. Preferably the valves should be turned ON and OFF by a reliable electronic irrigation controller that is easy to program and can carry out a wide variety of watering schedules. The goal is to uniformly distribute the optimum amount of water over a given area. The type, placement, and flow rates for each of the sprinklers are pre-selected when an irrigation system is designed and/or installed. The amount of water supplied by each sprinkler is largely determined by the size and configuration of its nozzle orifice(s), and water pressure that is supplied to the sprinkler.

Landscape irrigation systems typically include one or more solenoid operated valves that are turned ON and OFF by an electronic irrigation controller. The valves admit water to various subterranean branch lines usually made of PVC pipe that typically have several sprinklers connected to risers coupled to the branch lines at spaced intervals. Each combination of a solenoid valve and its associated sprinklers is referred to in the irrigation industry as a station or zone.

DETAILED DESCRIPTION

A modern electronic irrigation controller typically includes a microprocessor that executes one or more watering programs. The watering programs can be pre-programmed by the user via push buttons and/or rotary controls. The controller usually has an LCD or other display to facilitate programming by the user. Often the controller will include an EEPROM memory to maintain the watering program in the case of a power failure. The microprocessor controls the solenoid valves via suitable drivers and switching devices. The valves are opened and closed by the microprocessor in accordance with the pre-programmed run and cycle times for each of the stations.

Electronic irrigation controllers have gained increasing popularity. In these controllers, the base portion of the system contains the microprocessor and user actuated controls. Often the microprocessor and user actuated controls are in the form a user interface panel, which is often called a face pack. The face pack of many controllers is in a hinged portion so the user can see the face pack for normal programming, yet this hinged portion can be opened to allow access to the wiring hook up area of the irrigation controller. The wiring hook up area often includes a transformer or other power supply as well as a variety of modules or terminals for connecting to a variety of sensors as well as control wires to operate the irrigation valves.

Each station is often controlled by a corresponding station module which typically comprises a plastic housing that encloses and supports a station module circuit, as well as wire connection terminals for connecting wires to a plurality of solenoid actuated valves. Usually each station module circuit includes a plurality of triacs or other AC switching devices and can independently control a plurality of solenoid actuated valves, i.e., stations. The station modules contain pins, sockets, card edge connectors or some other standard form of connectors for allowing them to be inserted into slots or receptacles in either the housing that contains the microprocessor or a separate back panel hinged to the microprocessor housing. When the station modules are plugged into a modular expandable irrigation controller, they are mechanically supported and an electrical connection is made between the microprocessor and the driver. See for example, U.S. Pat. No. 6,721,630 B1 of Peter J. Woytowitz, assigned to Hunter Industries, Inc., the assignee of the present application. Some irrigation controllers have a fixed number of station terminals built into the controller and they do not have the station modules. Some irrigation controllers use a combination of fixed terminals plus expansion modules.

The advantage of an irrigation controller with a modular expandable configuration is that the controller need only be equipped with the minimum number of station modules that can control the total number of stations needed. Thus, for example, an irrigation system may have six zones, requiring only a single station module, while another may have fifty stations which might require nine station modules. Considerable cost savings are thus achieved. Moreover, if an irrigation system expands after initial installation because the landscaping has increased, additional station modules can be plugged into the controller. The station modules can also be removed and replaced if damaged, for example, during a lightning strike. In some modular expandable irrigation systems the base unit is capable of controlling a minimal number of stations without requiring the addition of any station modules. In others, such as the ProC™ irrigation controller manufactured and sold by Hunter Industries, Inc., at least a power module and one irrigation station module are plugged into the controller in order to operate any stations or zones.

Various manufacturers commercially produce modular expandable irrigation controllers. While the input controls and processor circuitry in these products vary in terms of their functional capabilities, the station modules do not. Conventional station modules include a type of AC switch, such as a triac, along with a circuit that can interpret commands from a microprocessor and drive the AC switch to the appropriate state. Some conventional station modules also include surge suppression components such as metal oxide varistors, gas tubes, or inductors.

Some conventional modular expandable irrigation controllers also provide multiple sensor interfaces, network communications, and flow sensing capabilities.

FIG. 1 illustrates an exemplary irrigation controller 10 with a front door in a closed position. FIG. 2 illustrates the irrigation controller 10 with the front door open to show a face pack mounted to the front side of an inner door and FIG. 3 illustrates the irrigation controller 10 with the front and inner doors open to show a wiring hook up area.

Referring to FIGS. 2 and 3, the irrigation controller 10, in an embodiment, comprises an outer housing 12 with radiused edges 14 including a generally box-shaped front door 16 hinged along its left vertical edge to the outer housing 12. The front door 16 may comprise radiused edges 18 that fit over the radiused edges 14 when the front door 16 is closed. A generally box-shaped back panel 20 (FIG. 3) is mounted to the interior area of the outer housing 12. The back panel 20 may include sides and other features that project inwardly into the outer housing 12. A lock 22 may be installed in the front door 16 that interacts with the back panel 20 or the outer housing 12 to keep the front door 16 securely closed unless unlocked and opened with an appropriate tool.

An inner door 24 is removably mounted to the back panel 20 or the outer housing 12. The inner door 24 includes a front panel 30 and a back panel 32. FIG. 9 illustrates the front panel 30 of the inner door 24 and FIG. 10 illustrates the back panel 32 of the inner door 24. Referring to FIGS. 7 and 8, the inner door 24 can be removed from the irrigation controller 10, in an embodiment, by retracting the hinge pin 70 (FIG. 7) to allow the inner door 24 to tilt out and be removed from the irrigation controller 10. A user may insert a finger into the hinge pin operator 72 (FIG. 8) and move it downward to retract the hinge pin 70 out of a mouthing hole (not illustrated) in the back panel 20.

A generally rectangular face pack 26 (FIG. 2) is removably mounted to the inner door 24 and is normally concealed by the front door 16 when not being accessed for programming. In an embodiment, the face pack 26 comprises a removable face pack 26. The face pack 26 comprises a plurality of manually actuable controls including push button switches 34, 35, 36, 37, 38 and 39 as well as a rotary push button switch 40, which can be manipulated in conjunction with numbers, words or graphic symbols indicated on a display 42 for entering or selecting a watering program as is well known to one of skill in the art of electronic irrigation controllers. Custom watering programs can be created by the user by manipulating the rotary push button switch 40 and selected ones of the push button switches 34, 35, 36, 37, 38 and 39. In an embodiment, the display 42 comprises a liquid crystal display. Other embodiments comprise other types of displays 42, such as LED display, video displays, or the like.

In an embodiment, the face pack 26 supports a main circuit board assembly 44 (FIG. 14) with a processor, microprocessor, or microcontroller 3202 (FIG. 32) for executing and implementing a stored watering program. An electrical connection is made between the face pack 26 and the components in the back panel 20 through an electrical cable (not illustrated) connecting the circuit board assembly 44 and the face pack connector 46 (FIG. 6). The circuitry inside the face pack 26 can be powered through the electrical cable or by a battery installed in the face pack 26 to allow a person or user to remove the face pack 26, unplug the electrical cable, and walk around the lawn, or garden area while entering a watering program or altering a pre-existing watering program. The stored watering program, for example, can be a complex set of run time and cycle programs, or a portion thereof, such as a simple five minute cycle routine for a single station.

Referring to FIG. 3, electrical connectors (not illustrated) in the ends of box-like station modules 48, receive corresponding output module connectors 50 a-50 j (FIG. 33B). The electrical connectors, in one embodiment, may be female male card edge connectors that mount to corresponding traces on the back plane printed circuit boards 106 and 108 (FIG. 33B). The intelligent station modules 48 are received in side-by-side fashion in a bay 52 formed in the back panel 20 (FIG. 3) which is separate from the face pack 26 that encloses the processor 3202. A fourth box-like flow expansion module 54 (FIG. 5) plugs onto its own bay 56 and interfaces with at least one flow sensor in the irrigation plumbing (not illustrated).

Locking slide bars 58 and 58 a (FIG. 4) with a gripping member 60 and 60 a, respectively, extend above the bays 52, 56 and may be moved back and forth between an unlocked position and a locked position. Projections (not illustrated) on the underside of the slide bars 58 and 58 a engage and disengage with complementary features (not illustrated) on the top surfaces of the modules to achieve the locked and unlocked states. The gripping members 60 and 60 a are alternately positioned adjacent to UNLOCKED and LOCKED indicia molded into the adjacent back panel structure to indicate the module connection status to the user. The positive module locking mechanism guards against partial or incomplete insertion of a module that could lead to open connections or shorts that would make a station or zone inoperable. The user is given visual and tactile feedback indicating that a positive lock has been established in the sense that each module has been fully inserted. The plurality of station modules 48 and flow expansion module 54 are simultaneously locked and unlocked with respect to their respective receptacles, which, in the embodiment illustrated in FIG. 3, are bays 52, 56 formed by side by side sections or regions of the bay formed in the back panel 20.

As used herein, the term “receptacle” refers to any structure and/or slot, region, area or section of any part of an irrigation controller frame or housing intended to receive and mechanically support, either internally or externally, a module and allow electrical contact and/or wireless connection between circuitry within the module and circuitry in the remainder of the controller. In the irrigation controller 10, each of the receptacles is defined by short sidewalls that divide a rear support wall of the rectangular bays 52 and 56 in the back panel 20 and includes the associated output module connectors.

In an embodiment, the back panel 20 comprises an outwardly opening plastic box that provides a support and a protective enclosure for removably receiving the modules 48 and 54. The back panel 20 may also support a power supply 62 and an additional terminal strip 64. The terminal strip 64 may be used as a connection point for various types of sensors, pump start relays, and common wires required for the irrigation site.

Referring to FIG. 3, the electric cable that electrically connects the face pack 26 to the back panel 20 may be plugged into a receptacle (not shown) in the bottom of the face pack 26 and the receptacle 46 in the back panel 20. The electrical cable may be routed in a cable carrier 66 and a cable storage cavity 68. The face pack 26 may be removed and repositioned so it advantageous for the electrical cable to have extra cable length to allow the face pack 26 to be removed and repositioned without disconnecting it from the electrical cable. In one embodiment, a cable storage cavity 68 provides a place to store the extra cable length.

The face pack 26 may be used to program and view program related data and other system information as well as provide diagnostic tools to the user. As seen in FIG. 3, when the inner door 24 is open to expose the wiring hook up area, the front side of the face pack 26 with the operator controls 34-40 and the display 42 are hidden from view and only the back side of the face pack 26 is visible to the user. In some instances, the user may want to see the front side of the face pack 26 to be able to utilize display 42 and control functions that may be beneficial in identifying problems with the irrigation system when the inner door 24 is open as illustrated in FIG. 3. In one embodiment, the face pack 26 may be removed from its mounting position on the front side of the inner door 24 and repositioned to the back side of the inner door 24.

FIG. 4 illustrates the irrigation controller 10 with the inner door 24 partially open and showing the face pack 26 tilted outward from the front side of the inner door 24; FIG. 5 illustrates the irrigation controller 10 with the inner door 24 partially open and showing the face pack 26 passing through the inner door 24; and FIG. 6 illustrates the face pack 26 mounted to the back side of the inner door 24.

As illustrated in FIGS. 4-6, users may insert their fingers into a recess 28 (FIG. 4) and pull the top of the face pack 26 away from the front panel 30 of the inner door 24. In some embodiments, the face pack 26 can be removed from the front side of the inner door 24 and moved to the inside or back side of the inner door 24 as illustrated in FIGS. 5 and 6.

FIGS. 7 and 8 are a side view and an isometric view, respectively, of the inner door 24 and illustrate the face pack 26 in a tilted position on the back panel 32 of the inner door 24. A user may pull the top of the face pack 26 away from the inner door 24 to place the face pack 26 in the position shown. If desired, the user could then lift the face pack 26 up and away from the inner door 24. A user could also place the face pack 26 into the inner door 24 to the position shown in FIGS. 7 and 8, then push on the upper area of the face pack 26 until it is against the inner door 24 for normal operation.

The circuit board assembly 44 may include all of the circuitry in the face pack 26. One or more metallic plates 84 may be installed to the inner surface 82. In an embodiment, the one or more metallic plates 84 are attracted to the one or more holding magnets 74 when the face pack 26 is installed in the inner door 24 to hold the face pack 26 against the inner door 24. The one or more metallic plates 84 may be attracted to the one or more holding magnets 74 when the face pack 26 is installed against either the front panel 30 or the back panel 32 of the inner door 24. In some embodiments, the holding magnets 74 may be loosely fit into the one or more magnet holding cavities 76 to allow the magnets to move towards the magnetic plates 84 when the face pack 26 is installed.

In an embodiment, a switch activation magnet 86 attaches to the inner door 24. In one embodiment, the switch activation magnet 86 may be installed to the inner surface of the front panel 30 of the inner door 24 (FIG. 11). A magnetically actuating switch, such as a reed switch, part number MDSM-4R-12-18 from Littlefuse Inc. or the like, or a magnetically actuating sensor, such as an IC Hall Effect Switch Part number A3212EUA-T from Allegro Micro systems or the like, may be installed on the circuit board assembly 44 of the face pack 26. Additionally, other switches that do not require a magnet could be used, such as an optical detector sensor part number SI1102-A-GMR from Silicone Labs, or the like, or a tactile switch part number 688-SKHHAJ from E-Switch, or the like. The magnetically actuating device 88 actuates when the switch activation magnet 86 is in close proximity.

In one embodiment, a reed switch 88 (FIG. 14) is installed on the circuit board assembly 44. The switch activation magnet 86 is in proximity with the reed switch 88, or other magnetically activated sensor when the face pack 26 is installed on one side of the inner door 24 such that the reed switch 88 is in an actuated state and the switch activation magnet 86 is far enough away from the reed switch 88 when the face pack 26 is installed on the other side of the inner door 24 such that the reed switch 88 is in an unactuated state. The face pack microprocessor 3202 reads the state of the reed switch 88 and, based on the state of the reed switch 88, the face pack microprocessor 3202 causes certain ones of a plurality of screens to be displayed on the display 42. In an embodiment, the plurality of screens comprise, for example, one of more of irrigation related screens, such as operation screens, Home Screen (Main Display), Run Manual Stations, Run Manual Program, Run Test Program, Program Start Times, Program Run Times.

For example, it may be helpful to a user to be able to view operating information on the display 42 when the face pack 26 is installed on the front face of the inner door 24 and the inner door 24 is in the closed position. It may be also helpful to a user to be able to view diagnostic information on the display 42 when the face pack 26 is installed on the back face of the inner door 24 and the inner door 24 is in the open position.

In one embodiment, when the face pack 26 is installed on the front side of the inner door 24, the reed switch 88 is not in close proximity to the switch activation magnet 86 such that the reed switch 88 is in its unactuated state and the face pack microcontroller 3202, based on the unactuated state of the reed switch 88, causes an irrigation related screen to be displayed on the display 42. The irrigation related screen comprises operating information for the irrigation controller 10. When the face pack 26 is installed on the back side of the inner door 24, the reed switch 88 is in close proximity to the switch activation magnet 86 such that the reed switch 88 is in its actuated state and the face pack microcontroller 3202, based on the actuated state of the reed switch 88, causes a system diagnostic screen to be displayed on the display 42. The system diagnostic screen comprises diagnostic information for the irrigation controller 10.

In another embodiment, the irrigation controller 10 can be configured to place the reed switch 88 in its actuated state when the face pack 26 is installed on the front side of the inner door 24 and the face pack microcontroller 3202, based on the actuated state of the reed switch 88, causes an irrigation related screen to be displayed on the display 42. The irrigation controller 10 is further configured to place the reed switch 88 in its unactuated state when the face pack 26 is installed on the back side of the inner door 24 and the face pack microcontroller 3202, based on the unactuated state of the reed switch 88, causes a diagnostic screen to be displayed on the display 42.

As used herein, “in close proximity” refers to the switch activation magnet 86 being close enough to the reed switch 88 such that the reed switch 88 detects a sufficient magnetic field from the switch activation magnet 86 to place the reed switch 88 in an actuated state. As used herein “not in close proximity” refers to the switch activation magnet 86 being far enough away from the reed switch 88 such that the reed switch 88 does not detect a strong enough magnetic field from the switch activation magnet 86 to place the reed switch 88 in the actuated state.

A locating feature is formed on at least one side of the face pack 26. FIG. 15 illustrates the right side of the face pack 26. Referring to FIG. 15, in one embodiment, generally rectangular locating bar 90 is formed on a first side of the back panel 78 of the face pack 26. As illustrated in FIG. 12, a second locating bar 90 a may be formed on a second side of the back panel 78. In one embodiment, the locating bar may have at least one radius end 92. In some embodiments the ends of the locating bars 90, 90 a may be the same shape. In other embodiments, the ends may be different shapes. The end may be radius, angular, or straight. In some embodiments, the locating feature may be circular, oval, triangular or any appropriate shape to locate the face pack 26 on the inner door 24.

FIG. 16 illustrates the back side of the inner door 24 and the face pack 26. Each of FIGS. 17-21 illustrates embodiments of the sectioned area AA on FIG. 16 that show the interaction between the face pack 26 and the inner door 24.

FIG. 17 shows the sectioned area AA of FIG. 16 without the face pack 26 installed. A first generally V-shaped pocket, notch, or groove 94 is formed in the inner edge of the inner door 24. A radius 96 is formed in the bottom of the V-shaped groove 94. In one embodiment, the radius 96 is substantially the same or just slightly larger than the radius 92 on the locating bar 90 on the face pack 26. In one embodiment, the V-shaped groove 94 may be duplicated on at least one other inner edge surface of the inner door 24. In some embodiments, one V-shaped groove 94 may be used.

FIG. 18 illustrates the face pack 26 mounted to the front panel 30 of the inner door 24. The locating bar 90 is seated in the V-shaped groove 94 to hold the face pack 26 in its proper horizontal location. Furthermore, at least one holding magnet 74 is attracting the at least one metallic plate 84 to hold the face pack 26 tight against the front panel 30.

FIG. 19 illustrates the face pack 26 mounted to the back panel 32 of the inner door 24. The locating bar 90 a is seated in the V-shaped groove 94 to hold the face pack 26 in its proper horizontal location. Furthermore, at least one holding magnet 74 is attracting the at least one metallic plate 84 to hold the face pack 26 tight against the back panel 32.

As illustrated in FIG. 20, a recessed area 98 is formed in the front panel 30 and a similar corresponding recess 100 is formed in the back panel 32 to allow the face pack 26 to pivot outwardly from the inner door 24. A clearance area 102 is formed in the edge of the inner door 24.

As illustrated in FIG. 21, the locating bar 90 can exit from the clearance areas 102 in the inner door 24 to allow a user to lift the face pack 26 away from the inner door 24. This procedure is reversed to install the face pack 26 into either side of the inner door 24. When a user needs to move the face pack 26 from one side of the inner door 24 to the other, the face pack 26 can pass through the opening 104 in the inner door 24. Passing the face pack 26 through the opening 104 allows the user to transfer the face pack 26 to a different location without disconnecting the power and communications cable.

FIGS. 22-24 are exemplary flow charts showing the effects of the reed switch positions. FIG. 22 illustrates an exemplary power-up process 2200. The process 2200 begins at step 2202 when the irrigation controller 10 is powered up.

At step 2204, the process 2200 checks the status of the reed switch 88. In an embodiment, the face pack microcontroller 3202 reads the state of the reed switch 88 at step 2204. The state of the reed switch 88 is either open or closed. Depending on the configuration of the reed switch 88, the open state comprises one of the actuated state and the unactuated state and the closed state comprises the other of the actuated state and the unactuated state.

When the state of the reed switch 88 is open, the process 2200 moves to step 2206, where a screen, such as a home screen, comprising operational information for the irrigation controller 10 is displayed on display 42. When the state of the reed switch 88 is closed, the process 2200 moves to step 2208, where a diagnostics screen comprising diagnostic information for the irrigation controller 10 is displayed on display 42.

In other embodiments, the home screen can be displayed when the state of the reed switch 88 is closed and the diagnostic screens can be displayed when the state of the reed switch 88 is open.

FIGS. 23 and 24 illustrate exemplary operational processes 2300 and 2400, respectively. Referring to FIG. 23, the process 2300 at step 2302 detects a closure of the reed switch 88. In an embodiment, the closure of the reed switch 88 causes an interrupt to be sent to the face pack microprocessor 3202 that indicates the closure of the reed switch 88. At step 2304, the process 2300 displays one or more diagnostic screens in response to the closure of the reed switch 88. In an embodiment, the face pack microprocessor 3202 initiates the display of the diagnostic screens in response to the interrupt.

Referring to FIG. 24, the process 2400 at step 2402 detects an opening of the reed switch 88.
